    摘要: Techniques for transmitting data in a manner to facilitate equalization at a receiver are described. Guard intervals are appended to data blocks such that each data block has a guard interval at the beginning of the data block and a guard interval at the end of the data block. Each guard interval may be discontinuous transmission (DTX), a polyphase sequence, or some other known sequence. Pilot is appended to each set of at least one data block. The data blocks, pilot, and guard intervals may be sent using various slot structures and are processed for transmission. The processing may include mapping the data blocks to at least one physical channel, channelizing the data blocks for each physical channel with a channelization code, combining all physical channels, and scrambling the combined data, pilot, and guard intervals with a scrambling code.

    摘要: Techniques for sending control information to support operation on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured with multiple CCs for carrier aggregation. The multiple CCs may be associated with different uplink-downlink configurations and may have different downlink subframes and uplink subframes. In one aspect, uplink control information (UCI) for a secondary CC (SCC) may be sent on a primary CC (PCC) based on a UCI transmission timeline for the PCC (and not based on a UCI transmission timeline for the SCC). For example, a downlink grant for the SCC may be sent based on a downlink grant transmission timeline for the PCC. In another aspect, uplink grants for an SCC may be sent on the PCC based on an uplink grant transmission timeline for the PCC (and not based on an uplink grant transmission timeline for the SCC).

    摘要: Systems and methodologies are described that facilitate determining control region parameters related to a plurality of carriers and/or coordinated multiple point (CoMP) access points. Wireless devices can receive control region parameters related to the carriers or CoMP access points from a serving access point over control channel resources. Additionally or alternatively, wireless devices can assume all carriers or CoMP access points have substantially the same control region as indicated in a control format indicator channel from the serving access point or based on a configured value.

    摘要: Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.

    摘要: Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

    摘要: Techniques for supporting high decoding throughput are described. A transmitter may encode a code block of data bits with a Turbo encoder. A receiver may perform decoding for the code block with a Turbo decoder having multiple soft-input soft-output (SISO) decoders. A contention-free Turbo interleaver may be used if the code block size is larger than a threshold size. A regular Turbo interleaver may be used if the code block size is equal to or smaller than the threshold size. The contention-free Turbo interleaver reorders the data bits in the code block such that information from the multiple SISO decoders, after interleaving or deinterleaving, can be written in parallel to multiple storage units in each write cycle without encountering memory access contention. The regular Turbo interleaver can reorder the data bits in the code block in any manner without regard to contention-free memory access.
